A coupon for 60% off has been awarded to the first 50 customers at a
new restaurant and you were 12th in line! Woohoo! If your bill was $12.80,
how much will you save

Answer:

$24.7875

Step-by-step explanation:

Step one:

given data

your bill before taxes and tip is $19.83

6% sales tax

tip equal to 19% of the original amount.

Required

The total expenses

Step two:

let the total expenses be y

let us calculate the cost of  tax and the tip

Tax

=6/100*19.83

=0.06*19.83

=$1.1898

Tip

=19/100*19.83

=0.19*19.83

=$3.7677

Total

Y= 19.83 +1.1898 +3.7677

Y= $24.7875

Step-by-step explanation:

area of rectangle =length x width

givens:

width=4 units

length=9 units

area=9x4=36 units squared

Answer:

[tex]\frac{10}{13}[/tex]

Step-by-step explanation:

In the question, the units of the length of both colored and white fabrics are not the same. So, convert the unit of the white fabrics into mm.

The length of colored fabric used = 13 mm.

The length of white fabric used = 1 cm

                                                     = 10 mm

To express the white fabric to colored fabric, we have;

[tex]\frac{length of white fabric used}{length of colored fabric used}[/tex] = [tex]\frac{10mm}{13mm}[/tex]

                               = [tex]\frac{10}{13}[/tex]

Thus, the amount of white fabric to colored fabric can be expressed as[tex]\frac{10}{13}[/tex].

Answer:

22=90 23=15 24=60 25=0.75 26=70 37=$0.58

Step-by-step explanation:

22. So, we can divide 360 kmh by 4 hours

so 360/4 =90

So 90 kmh in 1 hr

23

So, we can divide 3 packages by $15

so 15÷3 = $5

So $5 per package

24  So, we can divide 720 m by 12s

So, 720/12= 60

60 m in 1 s

25

So, we can divide $4.50 by 6

So, we get $0.75

26

So, we can divide 210 words by 3 min

So, 210÷3=70

70 words per minute

27

So, we can divide 23.20 by 40l

So, 23.20÷40 = 0.58

$0.58

Answer: I think is a function

Step-by-step explanation:

Answer:

The correct answer is B.

Step-by-step explanation:

Any point can be represented in polar form by using the notation:

[tex]A = (r, \theta)[/tex] (1)

And any polar function must satisfy the following definition:

[tex]r = f(\theta)[/tex]

Let [tex]r(\theta) = 4\cdot \cos 2\theta[/tex], where [tex]r[/tex] is the radial distance of any point of the curve from origin and [tex]\theta[/tex] is the direction of any point of the curve with respect to +x semiaxis, measured in radians.

Finally, we proceed to graph the function with the help of a graphing tool and attach the result.

Besides, we must remember that cosine is a bounded function, which means that domain and range in rectangular coordinates are represented by:

[tex]Dom\{f\} = [-4,4][/tex], [tex]Ran\{f\} = [-4,4][/tex]

Then, the correct answer is B.

Answer:

I think it is 4 white and 3 blue

Step-by-step explanation:

Because they have 3 cups of white then 6 cups of white so i think they multiplied it. Then they have 4 cups of blue then 8 cups of blue. So if you multiply it, it will give you the answer. I hope this is right and it helped and can you mark me brainliest!!!!!!!!

Answer:

By "make k as a subject", I assume you mean to solve for k?

If that is the case, then the answer is:

k = (c - a) / b

Step-by-step explanation:

Let's solve for k

a/k + b = c/k

Multiply both sides by k:

a + bk = c

Group terms containing k on the left:

bk = c - a

Divide both sides by k:

k = (c - a) / b

Step-by-step explanation:

Answer: y=17

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

52−2y=18

52+−2y=18

−2y+52=18

Step 2: Subtract 52 from both sides.

−2y+52−52=18−52

−2y=−34

Step 3: Divide both sides by -2.

−2y

−2

=

−34

Answer:

9.43 cm³

Step-by-step explanation:

Given that the surface area of the spherical scoop is 36π cm², we find its radius. The surface area of a sphere, A = 4πr² where r = radius

36π cm² = 4πr²

r² = 36π cm²/4π

r² = 9 cm²

r = √(9 cm²)

r = 3 cm

So, the volume of the spherical scoop of ice cream is thus V = 4πr³/3

= 4π(3 cm)³/3

= 4π(9 cm³)

= 36π cm³

The volume of the ice cream cone is V' = πr²h/3 where r = radius of cone = radius of spherical scoop = 3cm and h = height of cone = 11 cm

V' = π(3 cm)² × 11 cm/3

= 9π cm² × 11 cm/3

= 33π cm³

So, the volume of ice cream that will overflow is thus V - V' = 36π cm³ - 33π cm³

= 3π cm³

= 9.43 cm³
